I have various battery sizes and appliances I am trying to compare to determine the best Solar Home System for my purposes. I have converted all batteries capacities and appliances into watt hours for an apples to apples comparison. How can I determine how long it will take to deplete a battery (hours of operation) based on consumption (watts). I know resistance factors into the equation, but I am not sure how much.
IE: I have a battery that measures 4.5 Ah and 13v for 58.5 Wh and an appliance that consumes 5.5 W (12v)... How many hours of operation will I get?
